An Improved Quartz Microbalance. Applications to the Electrocrystallization and ‐dissolution of Nickel

Abstract

Abstract A transistorized Pierce‐Miller‐oscillator is described which can be used to excite a quartz vibrator in contact with a solution. Changes of the resonance frequency of the quartz induced by deposition or dissolution of substances on one of its surfaces can be measured. We also describe a simple teflon holder which allows fixation of the crystal in a position in which only one of its faces is in contact with the solution.—The influence of simultaneous gas evolution on the performance of the balance is discussed. Preliminary results on the role of hydrides during nickel deposition and dissolution are presented and compared with literature data.
